Mitigating Load Imbalance in Distributed Data Serving with Rack-Scale Memory Pooling
Babak Falsafi, Edouard Bugnion, Boris Robert Grot, Alexandros Daglis, Stanko Novakovic, Dmitrii Ustiugov
To provide low-latency and high-throughput guarantees, most large key-value stores keep the data in the memory of many servers. Despite the natural parallelism across lookups, the load imbalance, introduced by heavy skew in the popularity distribution of k ...
2019Prefetched Address Translation
Edouard Bugnion, Boris Robert Grot, Dmitrii Ustiugov
With explosive growth in dataset sizes and increasing machine memory capacities, per-application memory footprints are commonly reaching into hundreds of GBs. Such huge datasets pressure the TLB, resulting in frequent misses that must be resolved through a ...
ASSOC COMPUTING MACHINERY2019Design Guidelines for High-Performance SCM Hierarchies
Babak Falsafi, Edouard Bugnion, Alexandros Daglis, Javier Picorel Obando, Mark Johnathon Sutherland, Dionysios Pnevmatikatos, Dmitrii Ustiugov
With emerging storage-class memory (SCM) nearing commercialization, there is evidence that it will deliver the much-anticipated high density and access latencies within only a fewfactors of DRAM. Nevertheless, the latency-sensitive nature of memory-residen ...
ACM2018Flow control for Latency-Critical RPCs
Edouard Bugnion, Evangelos Marios Kogias
In today’s modern datacenters, the waiting time spent within a server’s queue is a major contributor of the end-to-end tail latency of μs-scale remote procedure calls. In traditional TCP, congestion control handles in-network congestion, while flow control ...
2018Persona: A High-Performance Bioinformatics Framework
James Richard Larus, Edouard Bugnion, Christos Kozyrakis, Stuart Anthony Byma, Sam David Whitlock
Next-generation genome sequencing technology has reached a point at which it is becoming cost-effective to sequence all patients. Biobanks and researchers are faced with an oncoming deluge of genomic data, whose processing requires new and scalable bioinfo ...
2017How to Measure the Killer Microsecond
Datacenter-networking research requires tools to both generate traffic and accurately measure latency and throughput. While hardware-based tools have long existed commercially, they are primarily used to validate ASICs and lack flexibility, e.g. to study n ...
Assoc Computing Machinery2017Hardware and Software Support for Virtualization
This book focuses on the core question of the necessary architectural support provided by hardware to efficiently run virtual machines, and of the corresponding design of the hypervisors that run them. Virtualization is still possible when the instruction ...
Mogan & Claypool2017The IX Operating System: Combining Low Latency, High Throughput, and Efficiency in a Protected Dataplan
Edouard Bugnion, Christos Kozyrakis, Georgios Prekas, Mia Primorac, Ana Klimovic
The conventional wisdom is that aggressive networking requirements, such as high packet rates for small messages and μs-scale tail latency, are best addressed outside the kernel, in a user-level networking stack. We present ix, a dataplane operating system ...
Association for Computing Machinery2016VNToR: Network Virtualization at the Top-of-Rack Switch
Edouard Bugnion, Georgios Ioannidis, Sam David Whitlock, Jonas Fietz
Cloud providers typically implement abstractions for net- work virtualization on the server, within the operating sys- tem that hosts the tenant virtual machines or containers. Despite being flexible and convenient, this approach has funda- mental problems ...
2016The Case for RackOut: Scalable Data Serving Using Rack-Scale Systems
Babak Falsafi, Edouard Bugnion, Boris Robert Grot, Alexandros Daglis, Stanko Novakovic
To provide low latency and high throughput guarantees, most large key-value stores keep the data in the memory of many servers. Despite the natural parallelism across lookups, the load imbalance, introduced by heavy skew in the popularity distribution of k ...
